As Representatives of the Several Underwriters

Dear Sirs:

1. Introductory. Interline Brands, Inc., a Delaware corporation ("Interline DE"), which will be the parent corporation of Interline Brands, Inc., a New Jersey corporation ("Interline NJ"), following the proposed merger ("Merger") of Interline NJ with and into Interline Subsidiary, Inc., a [Delaware] corporation and subsidiary of Interline DE (Interline DE, after the Merger, and Interline NJ, before the Merger, are referred to herein as the "Company"), proposes to issue and sell [ • ] shares ("Firm Securities") of its Common Stock ("Securities") and also proposes to issue and sell to the Underwriters, at the option of the Underwriters, an aggregate of not more than [ • ] additional shares ("Optional Securities") of its Securities as set forth below. The Firm Securities and the Optional Securities are herein collectively called the "Offered Securities". The Company hereby agrees with the several Underwriters named in Schedule A hereto ("Underwriters") as follows:

2. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the several Underwriters that:

(a) A registration statement (No. 333-116482) relating to the Offered Securities, including a form of prospectus, has been filed with the Securities and Exchange Commission ("Commission") and either (i) has been declared effective under the Securities Act of 1933 ("Securities Act") and is not proposed to be amended or (ii) is proposed to be amended by amendment or post-effective amendment. If such registration statement ("initial registration statement") has been declared effective, either (i) an additional registration statement ("additional registration statement") relating to the Offered Securities may have been filed with the Commission pursuant to Rule 462(b) ("Rule 462(b)") under the Securities Act and, if so filed, has become effective upon filing pursuant to such Rule and the Offered Securities all have been duly registered under the Securities Act pursuant to the initial registration statement and, if applicable, the additional registration statement or (ii) such an additional registration statement is proposed to be filed with the Commission pursuant to Rule 462(b) and will become effective upon filing pursuant to such Rule, and upon such filing the Offered Securities will all have been duly registered under the Securities Act pursuant to the initial registration statement and such additional registration statement. If the Company does not propose to amend the initial registration statement or if an additional registration statement has been filed and the Company does not propose to amend it, and if any post-effective amendment to either such registration statement has been filed with the Commission prior to the execution and delivery of this Agreement, the most recent amendment (if any) to each such registration statement has been declared effective by the Commission or has become effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the Securities Act or,

in the case of the additional registration statement, Rule 462(b). For purposes of this Agreement, "Effective Time" with respect to the initial registration statement or, if filed prior to the execution and delivery of this Agreement, the additional registration statement means (i) if the Company has advised the Representatives that it does not propose to amend such registration statement, the date and time as of which such registration statement, or the most recent post-effective amendment thereto (if any) filed prior to the execution and delivery of this Agreement, was declared effective by the Commission or has become effective upon filing pursuant to Rule 462(c), or (ii) if the Company has advised the Representatives that it proposes to file an amendment or post-effective amendment to such registration statement, the date and time as of which such registration statement, as amended by such amendment or post-effective amendment, as the case may be, is declared effective by the Commission. If an additional registration statement has not been filed prior to the execution and delivery of this Agreement but the Company has advised the Representatives that it proposes to file one, "Effective Time" with respect to such additional registration statement means the date and time as of which such registration statement is filed and becomes effective pursuant to Rule 462(b). "Effective Date" with respect to the initial registration statement or the additional registration statement (if any) means the date of the Effective Time thereof. The initial registration statement, as amended at its Effective Time, including all information contained in the additional registration statement (if any) and deemed to be a part of the initial registration statement as of the Effective Time of the additional registration statement pursuant to the General Instructions of the Form on which it is filed and including all information (if any) deemed to be a part of the initial registration statement as of its Effective Time pursuant to Rule 430A(b) ("Rule 430A(b)") under the Securities Act, is hereinafter referred to as the "Initial Registration Statement". The additional registration statement, as amended at its Effective Time, including the contents of the initial registration statement incorporated by reference therein and including all information (if any) deemed to be a part of the additional registration statement as of its Effective Time pursuant to Rule 430A(b), is hereinafter referred to as the "Additional Registration Statement". The Initial Registration Statement and the Additional Registration Statement are herein referred to collectively as the "Registration Statements" and individually as a "Registration Statement". The form of prospectus relating to the Offered Securities, as first filed with the Commission pursuant to and in accordance with Rule 424 ("Rule 424") under the Securities Act or (if no such filing is required) as included in a Registration Statement, is hereinafter referred to as the "Prospectus". No document has been or will be prepared or distributed in reliance on Rule 434 under the Securities Act.

(b) If the Effective Time of the Initial Registration Statement is prior to the execution and delivery of this Agreement: (i) on the Effective Date of the Initial Registration Statement, the Initial Registration Statement conformed in all material respects to the requirements of the Securities Act and the rules and regulations of the Commission ("Rules and Regulations") and did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not misleading, (ii) on the Effective Date of the Additional Registration Statement (if any), each Registration Statement conformed, or will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations and did not include, or will not include, any untrue statement of a material fact and did not omit, or will not omit, to state any material fact necessary in order to make the statements therein not misleading and (iii) on the date of this Agreement, the Initial Registration Statement and, if the Effective Time of the Additional Registration Statement is prior to the execution and delivery of this Agreement, the Additional Registration Statement each conforms, and at the time of filing of the Prospectus pursuant to Rule 424 or (if no such filing is required) at the Effective Date of the Additional Registration Statement in which the Prospectus is included, each Registration Statement and the Prospectus will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations, and neither of such documents includes, or will include, any untrue

statement of a material fact or omits, or will omit, to state any material fact necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading. If the Effective Time of the Initial Registration Statement is subsequent to the execution and delivery of this Agreement: on the Effective Date of the Initial Registration Statement, the Initial Registration Statement and the Prospectus will conform in all material respects to the requirements of the Securities Act and the Rules and Regulations, neither of such documents will include any untrue statement of a material fact or will omit to state any material fact necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and no Additional Registration Statement has been or will be filed. The two preceding sentences do not apply to statements in or omissions from a Registration Statement or the Prospectus based upon written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 7(b) hereof.

(c) Interline DE has been duly incorporated and is an existing corporation in good standing under the laws of the State of Delaware; Interline NJ has been duly incorporated and is an existing corporation in good standing under the laws of the State of New Jersey, with power and authority (corporate and other) to own its properties and conduct its business as described in the Prospectus; and Interline NJ is duly qualified to do business as a foreign corporation in good standing in all other jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified or in good standing would not individually or in the aggregate have a material adverse effect on the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries, taken as a whole ("Material Adverse Effect").

(d) Each subsidiary of the Company has been duly incorporated and is an existing corporation in good standing under the laws of the jurisdiction of its incorporation, with power and authority (corporate and other) to own its properties and conduct its business as described in the Prospectus; and each subsidiary of the Company is duly qualified to do business as a foreign corporation in good standing in all other jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified or in good standing would not individually or in the aggregate have a Material Adverse Effect; all of the issued and outstanding capital stock of each subsidiary of the Company has been duly authorized and validly issued and is fully paid and nonassessable; and the capital stock of each subsidiary owned by the Company, directly or through subsidiaries, is owned free from liens, encumbrances and defects, except for the liens on or pledges of the capital stock of certain subsidiaries of the Company in favor of the lenders under or related to the Credit Agreement, dated as of May 29, 2003, among the Company, the lender parties thereto, Credit Suisse First Boston LLC and JPMorgan Chase Bank, as amended ("Credit Agreement"). Assuming the consummation of the Merger, a list of all subsidiaries of the Company, indicating their respective jurisdictions of formation or organization and the Company's direct or indirect ownership therein, is attached hereto as Schedule B.

(e) Assuming the Merger has been consummated and the Amended and Restated Certificate of Incorporation of the Company, in substantially the form filed as an exhibit to the Registration Statement, has become effective, the Offered Securities and all other outstanding shares of capital stock of the Company have been duly authorized; all outstanding shares of capital stock of the Company are, and when the Offered Securities have been delivered and paid for in accordance with this Agreement on each Closing Date (as defined below), such Offered Securities will have been validly issued, fully paid and nonassessable and will conform in all material respects to the

(j) The execution, delivery and performance of this Agreement, and the issuance and sale of the Offered Securities will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, (i) any statute, any rule, regulation or order of any governmental agency or body or any court, domestic or foreign, having jurisdiction over the Company or any subsidiary of the Company or any of their properties, or (ii) any agreement or instrument to which the Company or any such subsidiary is a party or by which the Company or any such subsidiary is bound or to which any of the properties of the Company or any such subsidiary is subject, or (iii) the charter or by-laws of the Company or any such subsidiary, except, in the case of subclauses (i) and (ii), such breaches, violations and defaults that would not individually or in the aggregate have a Material Adverse Effect; and the Company has the corporate power and authority to authorize, issue and sell the Offered Securities as contemplated by this Agreement.

3. Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to sell to the Underwriters, and the Underwriters agree, severally and not jointly, to purchase from the Company, at a purchase price of $[ • ] per share, the respective numbers of shares of Firm Securities set forth opposite the names of the Underwriters in Schedule A hereto.

The Company will deliver against payment of the purchase price the Firm Securities in the form of one or more permanent global Securities in definitive form (the "Firm Global Securities") deposited with the Trustee as custodian for The Depository Trust Company ("DTC") and registered in the name of Cede & Co., as nominee for DTC. Interests in any permanent global Securities will be held only in book-entry form through DTC, except in the limited circumstances described in the Prospectus. Payment for the Firm Securities shall be made by the Underwriters in Federal (same day) funds by official bank check or checks or wire transfer to an account at a bank acceptable to the Representatives drawn to the order of Interline Brands, Inc. at the office of Cravath, Swaine & ▇▇▇▇▇ LLP at 10:00 A.M., (New York time), on [ • ], 2004 or at such other time not later than seven full business days thereafter as the Representatives and the Company determine, such time being herein referred to as the "First Closing Date", against delivery to the Trustee as custodian for DTC of the Firm Global Securities representing all of the Firm Securities.

In addition, upon written notice from the Representatives given to the Company from time to time not more than 30 days subsequent to the date of the Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per Security to be paid for the Firm Securities. The Company agrees to sell to the Underwriters the number of shares of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of each Underwriter in the same proportion as the number of shares of Firm Securities set forth opposite such Underwriter's name bears to the total number of shares of Firm Securities (subject to adjustment by the Representatives to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representatives to the Company.

Each time for the delivery of and payment for the Optional Securities, being herein referred to as an "Optional Closing Date", which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a "Closing Date"), shall be determined by the Representatives but shall be not later than five full business days after written notice of election to purchase Optional Securities is given. The Company will deliver against payment of the purchase price the Optional Securities being purchased on each Optional Closing Date in the form of one or more permanent global securities in definitive form (each, an "Optional Global Security") deposited with the Trustee as custodian for DTC and registered in the name of Cede & Co., as nominee for DTC. Payment for such Optional Securities shall be made by the Underwriters in Federal (same day) funds by official bank check or checks or wire transfer to an account at a bank acceptable to the Representatives drawn to the order of Interline Brands, Inc. at the office of Cravath, Swaine & ▇▇▇▇▇ LLP, against delivery to the Trustee as custodian for DTC of the Optional Global Securities representing all of the Optional Securities being purchased on such Optional Closing Date.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Prospectus.

5. Certain Agreements of the Company. The Company agrees with the several Underwriters that:

(a) If the Effective Time of the Initial Registration Statement is prior to the execution and delivery of this Agreement, the Company will file the Prospectus with the Commission pursuant to and in accordance with subparagraph (1) (or, if applicable and if consented to by the Representatives, subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the second business day following the execution and delivery of this Agreement or (B) the fifteenth business day after the Effective Date of the Initial Registration Statement.

The Company will advise the Representatives promptly of any such filing pursuant to Rule 424(b). If the Effective Time of the Initial Registration Statement is prior to the execution and delivery of this Agreement and an additional registration statement is necessary to register a portion of the Offered Securities under the Securities Act but the Effective Time thereof has not occurred as of such execution and delivery, the Company will file the additional registration statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date of this Agreement or, if earlier, on or prior to the time the Prospectus is printed and distributed to any Underwriter, or will make such filing at such later date as shall have been consented to by the Representatives.

(b) The Company will advise the Representatives promptly of any proposal to amend or supplement the initial or any additional registration statement as filed or the related prospectus or the Initial Registration Statement, the Additional Registration Statement (if any) or the Prospectus and will not effect such amendment or supplementation without the Representatives' consent, which consent shall not be unreasonably withheld; and the Company will also advise the Representatives promptly of the effectiveness of each Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement) and of any amendment or supplementation of a Registration Statement or the Prospectus and of the institution by the Commission of any stop order proceedings in respect of a Registration Statement (upon receipt of notice thereof) and will use its commercially reasonable efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(c) If, at any time when a prospectus relating to the Offered Securities is required to be delivered under the Securities Act in connection with sales by any Underwriter or dealer, any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Prospectus to comply with the Securities Act, the

Company will promptly notify the Representatives of such event and will promptly prepare and file with the Commission, at its own expense, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives' consent to, nor the Underwriters' delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 6.

(d) As soon as practicable, but not later than the Availability Date (as defined below), the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the Effective Date of the Initial Registration Statement (or, if later, the Effective Date of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Securities Act. For the purpose of the preceding sentence, "Availability Date" means the 45th day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Date, except that, if such fourth fiscal quarter is the last quarter of the Company's fiscal year, "Availability Date" means the 90th day after the end of such fourth fiscal quarter.

(e) The Company will furnish to the Representatives copies of each Registration Statement (three of which will be signed and will include all exhibits), each related preliminary prospectus, and, so long as a prospectus relating to the Offered Securities is required to be delivered under the Securities Act in connection with sales by any Underwriter or dealer, the Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Representatives reasonably request. The Prospectus shall be so furnished on or prior to 3:00 P.M., New York time, on the business day following the later of the execution and delivery of this Agreement or the Effective Time of the Initial Registration Statement. All other documents shall be so furnished as soon as reasonably available. The Company will pay the reasonable expenses of printing and distributing to the Underwriters all such documents.

(f) The Company will use its commercially reasonable efforts to arrange for the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives designate and will use its commercially reasonable efforts to continue such qualifications in effect so long as required for the distribution; provided that the Company will not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction as a result of any such qualification.

(g) The Company will pay all expenses incident to the performance of its obligations under this Agreement, for any filing fees and other expenses (including reasonable fees and disbursements of counsel) incurred in connection with qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives reasonably designate and the printing of memoranda relating thereto, for the filing fee incident to the review by the National Association of Securities Dealers, Inc. ("NASD") of the Offered Securities, for any travel expenses of the Company's officers and employees and any other expenses of the Company in connection with attending or hosting meetings with prospective purchasers of the Offered Securities, for the cost of any aircraft chartered in connection with attending or hosting such meetings and for expenses incurred in distributing preliminary prospectuses and the Prospectus (including any amendments and supplements thereto) to the Underwriters.

(h) For the period specified below (the "Lock-Up Period"), the Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any additional shares of its Securities or securities convertible into or exchangeable or exercisable for any shares of its Securities, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the Representatives, except (i) for the issuance of common shares or stock options in Interline DE to holders of preferred shares, common shares or stock options in Interline NJ pursuant to the terms of [the merger agreement dated [ • ], 2004, among Interline DE, Interline NJ and [ • ]] entered into in connection with the Merger, (ii) grants of employee stock options pursuant to the terms of a plan in effect on the date hereof or otherwise approved by the Company's Board of Directors prior to the First Closing Date in the form and on such terms as described in the Prospectus under the heading "Management—Incentive Plans—2004 Equity Incentive Plan," (iii) issuances of shares of its Securities pursuant to the exercise of such options, (iv) the exercise of any other employee stock options outstanding on the date hereof or issuances of shares of its Securities pursuant to the Company's dividend reinvestment plan or (v) as consideration for the acquisition of assets or securities of another business or entity; provided, however, that (x) no such acquisition of assets or securities of another business or entity shall occur prior to 90 days after the date of the Prospectus; (y) the recipients of such shares of Securities agree to be bound by the provisions of this Section 5(h); and (z) the value of such shares of Securities used as consideration pursuant to this clause shall not exceed 15% of the market capitalization of the Company on the date of such transaction. The initial Lock-Up Period will commence on the date of this Agreement and continue for 180 days after the date of the Prospectus or such earlier date that the Representatives consent to in writing; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or material news or a material event relating to the Company occurs or (2) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension.

6. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Firm Securities on the First Closing Date and the Optional Securities to be purchased on each Optional Closing Date will be subject to the accuracy of the representations and warranties on the part of the Company herein on the date hereof and on the First Closing Date and each Optional Closing Date, to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

(a) The Representatives shall have received a letter, dated the date of delivery thereof (which, if the Effective Time of the Initial Registration Statement is prior to the execution and delivery of this Agreement, shall be on or prior to the date of this Agreement or, if the Effective Time of the Initial Registration Statement is subsequent to the execution and delivery of this Agreement, shall be prior to the filing of the amendment or post-effective amendment to the registration statement to be filed shortly prior to such Effective Time), of Deloitte & Touche LLP confirming that they are independent public accountants within the meaning of the Act and the applicable Rules and Regulations thereunder and stating to the effect that:

(i) in their opinion the financial statements examined by them and included in the Registration Statements comply as to form in all material respects with the applicable accounting requirements of the Act and the related Rules and Regulations;

(ii) they have performed the procedures specified by the American Institute of Certified Public Accountants for a review of interim financial information as described in Statement of Auditing Standards No. 100, Interim Financial Information, on the unaudited financial statements included in the Registration Statements;

(iii) on the basis of the review referred to in clause (ii) above, a reading of the latest available interim financial statements of the Company, inquiries of officials of the Company who have responsibility for financial and accounting matters and other specified procedures, nothing came to their attention that caused them to believe that:

(A) the unaudited financial statements included in the Registration Statements do not comply as to form in all material respects with the applicable accounting requirements of the Act and the related Rules and Regulations or any material modifications should be made to such unaudited financial statements for them to be in conformity with generally accepted accounting principles;

(B) at the date of the latest available balance sheet read by such accountants, or at a subsequent specified date not more than three business days prior to the date of this Agreement, there was any change in the common stock or any increase in total debt or total stockholders' deficiency of the Company and its consolidated subsidiaries or there was any decrease in consolidated net current assets, as compared with amounts shown on the latest balance sheet included in the Prospectus; or

(C) for the period from the closing date of the latest income statement included in the Prospectus to the closing date of the latest available income statement read by such accountants, or at a subsequent specified date not more than three business days prior to the date of this Agreement, there were any decreases, as compared with the corresponding period of the previous year, in consolidated net sales or increases, as compared with the corresponding period of the previous year, in net loss applicable to common stockholders,

except in all cases set forth in clauses (B) and (C) above for changes, increases or decreases which are described in such letter; and

(iv) they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other financial information contained in the Registration Statements (in each case to the extent that such dollar amounts, percentages and other financial information are derived from the general accounting records of the Company and its subsidiaries subject to the internal controls of the Company's accounting system or are derived directly from such records by analysis or computation) with the results obtained from inquiries, a reading of such general accounting records and other procedures specified in such letter and have found such dollar amounts, percentages and other financial information to be in agreement with such results, except as otherwise specified in such letter;

(v) they have read the unaudited pro forma condensed consolidated financial statements included in the Registration Statements, and after inquiries with certain officials of the Company who have responsibility for financial and accounting matters and other specified procedures, nothing came to their attention that caused them to believe that such financial statements do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X and that the pro forma adjustments have not been property applied to the historical amounts in the compilation of those statements;

(vi) they have read and compared the executive compensation information included in the Registration Statements with the requirements of item 402 of Regulation S-K and inquired of certain officials of the Company who have responsibility for financial and accounting

matters whether such executive compensation information conforms in all material respects with the disclosure requirements of item 402 of Regulation S-K, and that nothing came to their attention that caused them to believe that such information did not conform in all material respects with the disclosure requirements of Regulation S-K; and

(vii) they have read and compared the financial information included in the Registration Statements under the heading "Selected Historical Consolidated Financial Data" with the requirements of item 301 of Regulation S-K and inquired of certain officials of the Company who have responsibility for financial and accounting matters whether such financial information conforms in all material respects with the disclosure requirements of item 301 of Regulation S-K, and that nothing came to their attention that caused them to believe that such information did not conform in all material respects with the disclosure requirements of Regulation S-K.

For purposes of this subsection, (i) if the Effective Time of the Initial Registration Statement is subsequent to the execution and delivery of this Agreement, "Registration Statements" shall mean the initial registration statement as proposed to be amended by the amendment or post-effective amendment to be filed shortly prior to its Effective Time, (ii) if the Effective Time of the Initial Registration Statement is prior to the execution and delivery of this Agreement but the Effective Time of the Additional Registration is subsequent to such execution and delivery, "Registration Statements" shall mean the Initial Registration Statement and the additional registration statement as proposed to be filed or as proposed to be amended by the post-effective amendment to be filed shortly prior to its Effective Time, and (iii) "Prospectus" shall mean the prospectus included in the Registration Statements.

(b) If the Effective Time of the Initial Registration Statement is not prior to the execution and delivery of this Agreement, such Effective Time shall have occurred not later than 10:00 P.M., New York time, on the date of this Agreement or such later date as shall have been consented to by the Representatives. If the Effective Time of the Additional Registration Statement (if any) is not prior to the execution and delivery of this Agreement, such Effective Time shall have occurred not later than 10:00 P.M., New York time, on the date of this Agreement or, if earlier, the time the Prospectus is printed and distributed to any Underwriter, or shall have occurred at such later date as shall have been consented to by the Representatives. If the Effective Time of the Initial Registration Statement is prior to the execution and delivery of this Agreement, the Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 5(a) of this Agreement. Prior to such Closing Date, no stop order suspending the effectiveness of a Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or the Representatives, shall be contemplated by the Commission.

(c) Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as one enterprise which, in the judgment of a majority in interest of the Underwriters including the Representatives, is material and adverse and makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Offered Securities; (ii) any downgrading in the rating of any debt securities or preferred stock issued or guaranteed by the Company by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities or preferred stock issued or guaranteed by the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating); (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of a majority in interest of the Underwriters including the Representatives, be likely to

prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on The New York Stock Exchange, or any setting of minimum prices for trading on such exchange; (v) any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (vi) any banking moratorium declared by U.S. Federal or New York authorities; (vii) any major disruption of settlements of securities or clearance services in the United States or (viii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of a majority in interest of the Underwriters including the Representatives, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the public offering or the sale, payment or delivery of the Offered Securities.

(d) The Representatives shall have received an opinion, dated the First Closing Date, of ▇▇▇▇, Weiss, Rifkind, ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Company, substantially in the form of Exhibit A hereto.

(g) The Representatives shall have received a certificate, dated the First Closing Date, of the President or any Vice President and a principal financial or accounting officer of the Company in which such officers, to the best of their knowledge after reasonable investigation, shall state that: the representations and warranties of the Company in this Agreement are true and correct in all material respects; the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the First Closing Date in all material respects; to their knowledge, no stop order suspending the effectiveness of any Registration Statement has been issued and no proceedings for that purpose have been instituted or are contemplated by the Commission; the Additional Registration Statement (if any) satisfying the requirements of subparagraphs (1) and (3) of Rule 462(b) was filed pursuant to Rule 462(b), including payment of the applicable filing fee in accordance with Rule 111(a) or (b) under the Securities Act, prior to the time the Prospectus was printed and distributed to any Underwriter; and, subsequent to the dates of the most recent financial statements in the Prospectus, there has been no change, nor any developments or events involving a prospective change, that would individually or in the aggregate have a Material Adverse Effect, except as set forth in or contemplated by the Prospectus or as described in such certificate.

(h) The Representatives shall have received a letter, dated the First Closing Date, of Deloitte & Touche LLP which meets the requirements of subsection (a) of this Section, except that the specified date referred to in such subsection will be a date not more than three days prior to the First Closing Date for the purposes of this subsection.

(j) With respect to any purchase of Optional Securities, the Representatives shall have received

(i) a certificate, dated such Optional Closing Date, of the President or any Vice President and a principal financial or accounting officer of the Company in which such officers shall state that the Offered Securities delivered on such Optional Closing Date have been duly and validly authorized, executed, issued and delivered by the Company in accordance with this Agreement, are fully paid and nonassessable and conform in all material respects to the description thereof contained in the Prospectus; and the stockholders of the Company have no preemptive rights with respect to such Offered Securities.

(ii) an opinion, dated such Optional Closing Date, of ▇▇▇▇, Weiss, Rifkind, ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Company, to the effect that the Offered Securities delivered on such Optional Closing Date have been duly and validly authorized, executed, issued and delivered by the Company in accordance with this Agreement and are fully paid and nonassessable and conform in all material respects to the description thereof contained in the Prospectus; and, to such counsel's knowledge, the stockholders of the Company have no preemptive rights with respect to the Offered Securities.

(k) The Merger shall have been consummated to the reasonable satisfaction of the Representatives.

(l) The Company shall have obtained the necessary consent to consummate the transactions contemplated by this Agreement (including the application of the net proceeds from the sale of the Offered Securities as described in the Prospectus) from the lenders under the Credit Agreement and the stockholders of the Company pursuant to the Amended and Restated Shareholders' Agreement of the Company, dated as of September 29, 2000, as amended.

The Company will furnish the Representatives with such conformed copies of such opinions, certificates, letters and documents as the Representatives reasonably request. The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder.

7. Indemnification and Contribution. (a) The Company will indemnify and hold harmless each Underwriter, its partners, affiliates, members, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein (in the case of the Prospectus or any amendment or supplement thereto, or any related preliminary prospectus, in the light of the circumstances under which they were made) not misleading, including any losses, claims, damages or liabilities arising out of or based upon the Company's failure to perform its obligations under Section 5(c) of this Agreement, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below; and provided further, that with respect to any untrue statement or alleged untrue statement in or omission or alleged omission from any preliminary prospectus the indemnity agreement

contained in this subsection (a) shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased the Offered Securities concerned, to the extent that a prospectus relating to such Offered Securities was required to be delivered by such Underwriter under the Act in connection with such purchase and any such loss, claim, damage or liability of such Underwriter results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Offered Securities to such person, a copy of the Prospectus if any such untrue statement, alleged untrue statement, omission or alleged omission was corrected in the Prospectus and if the Company had previously furnished copies thereof to such Underwriter.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, its directors and officers and each person, if any who controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary in order to make the statements therein (in the case of the Prospectus or any amendment or supplement thereto, or any related preliminary prospectus, in the light of the circumstances under which they were made) not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of (i) the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the [ • ] paragraphs under the caption "Underwriting" and (ii) the following information in the Prospectus furnished on behalf of [ • ] under the caption [ • ].

(c) Promptly after receipt by an indemnified party under this Section or Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above or Section 9, notify the indemnifying party of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above or Section 9 except to the extent that it has been materially prejudiced (including through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above or Section 9. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel approved by such indemnified party, which approval shall not be unreasonably withheld (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section or Section 9, as the case may be, for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such action, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party, or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the

indemnifying party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified parties, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company and any control persons of the Company shall be designated in writing by the Company. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or failure to act by or on behalf of an indemnified party. No indemnifying party shall be liable for any settlement or compromise of, or consent to the entry of judgment with respect to, any such action or claim effected without its consent, unless such indemnifying party has failed, upon request by the indemnified party pursuant to this Section 7, to reimburse the indemnified party for legal expenses due pursuant to this Section 7 or Section 9 within thirty days of such request.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total discounts, fees and commissions received by such Underwriter exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section or Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and

conditions, to each person, if any, who controls any Underwriter or the QIU (as hereinafter defined) within the meaning of the Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed a Registration Statement and to each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act.

8. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

9. Qualified Independent Underwriter. The Company hereby confirms that at its request Credit Suisse First Boston LLC has without compensation acted as "qualified independent underwriter" (in such capacity, the "QIU") within the meaning of Rule 2720 of the Conduct Rules of the National Association of Securities Dealers, Inc. in connection with the offering of the Offered Securities. The Company will indemnify and hold harmless the QIU against any losses, claims, damages or liabilities, joint or several, to which the QIU may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon the QIU's acting (or alleged failing to act) as such "qualified independent underwriter" and will reimburse the QIU for any legal or other expenses reasonably incurred by the QIU in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company shall remain responsible for the out-of-pocket expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company and the Underwriters pursuant to Section 7 and the obligations of the Company pursuant to Section 9 shall remain in effect, and if any Offered Securities have been

purchased hereunder the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 8 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 6(c), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or faxed and confirmed to the Representatives c/o Credit Suisse First Boston LLC, Eleven ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇, Attention: Transactions Advisory Group, and ▇▇▇▇▇▇ Brothers Inc., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: [ • ], or, if sent to the Company, will be mailed, delivered or faxed and confirmed to it at ▇▇▇ ▇. ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 7 will be mailed, delivered or faxed and confirmed to such Underwriter.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder.

13. Representation of Underwriters. The Representatives will act for the several Underwriters in connection with this financing, and any action under this Agreement taken by the Representatives jointly will be binding upon all the Underwriters.

14. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of laws.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

If the foregoing is in accordance with the Representatives' understanding of our agreement, kindly sign and return to the Company one of the counterparts hereof, whereupon it will become a binding agreement between the Company and the several Underwriters in accordance with its terms.
